Avanti is powered by Gui4Cligui4cli.com and by its own additional dll's which are all written in C and C++.
Therefore Avanti is small
and relies only on the basic Windows OS resources.
It should run without problems on Windows XP and Vista.

Avanti GUI is a free front-end for FFmpeg with the option to insert AviSynth as pre-processor.
It offers user friendly control over all basic and advanced FFmpeg options. A number of template examples are included. No need to be familiar with AviSynth to use the predefined Avanti/AviSynth pre-processor options. Avanti comes as a portable application packed in a zip folder and doesn't require installation. No adware or internet access. (more ...).

We use the Zeranoe FFmpeg builds as reference during Avanti development.
These builds are frequently updated and include all required extra libraries,
FFplay and the full html documentation.

You can download the latest static Win32 build here and copy ffmpeg.exeand ffplay.exe to the ffmpeg folder at your Avanti install directory. If the latest build fails with the current Avanti version, try an older build from this archive.

The last FFmpeg version we checked out successfully with Avanti 0.9.3 is ...

ffmpeg version N-71959-g9253cc4

Zeranoe archive date May 7, 2015

Note that this concerns the basic functioning and that there is no guarantee
that all FFmpeg codecs and options will work as to be expected.
